Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612630, here are decompositions:

3 + 31612627 = 31612630
11 + 31612619 = 31612630
41 + 31612589 = 31612630
47 + 31612583 = 31612630
83 + 31612547 = 31612630
149 + 31612481 = 31612630
239 + 31612391 = 31612630
317 + 31612313 = 31612630

Showing the first eight; more decompositions exist.
